Filter percent charts

[JulienPalard]

I just got an idea, about the percent option about charts:

The actual "percent" mode only permit to compare a volume with other displayed volumes.

What about an option to permit to display a percentage of a volume alone ?

It's obscure, but let's take an example:

We all have at least "notice", "warning", and "errors" messages, and it's cool to display them in a single area chart, in "percent" mode, to have a view of how the proportion of each kind of messages change, independently of the volume (say day vs night).

Why not allowing to display a percentage area chart of say "error" only ? It would be exactly the same as displaying the tree values, but with the other values hidden.

Doing so permit to re-scale the Y axis, instead of 0-100% kibana would be able to display a scaled axis, say we almost never hit 5% of errors, kibana will choose a 0-8% Y axis to display something more readable than just a flatline.

In Kibana 4.1, you should be able to set the y axis bounds on percent charts that will allow you to do what you want here. So, if you wanted to set the percentage scale to display values between 0 and 8%, you can. Although the values from that range will fill the screen. If you wish to see the fluctuation, you can play around with the axis bounds.

OK for the bounding of Y axis, but what about hiding other areas ? To have a "white background" instead of "another value" in top of the displayed area ?

It would be interesting to add view-level toggling of series. I think there's a lot we could do with interactions to make that happen.

Another similar example.

HTTP status error rates. When storing web server logs, have an error rate chart 50x codes vs total requests.

Currently I'm using Kibana 4.1 Y axis bounds in percentage but it won't scale automatically so I'll need to change the bounds if the rate grows up the upper bound limit.

The use-cases described in this ticket can be solved with bucket scripts, by using a simple division between two aggregation. You can achieve that nowadays in Visual Builder (TSVB) via the "Filter Ratio" aggregation, and in general that can be achieved via Bucket scripts aggregations for which we have another open ticket (#4707).
